NT-proBNP provides diagnostic and prognostic information in heart syndromes but its role in cancer has not yet been established. The prognostic value of NT-proBNP was prospectively studied in 104 non-Hodgkin lymphoma (NHL) patients treated with chemotherapy. Echocardiography and NT-proBNP were determined prior to treatment. In multivariate analysis, NT-proBNP ≥ 900 pg/ml was the variable with higher risk of death (adjusted hazard ratio 11.1; 95% CI 3.8-32.9; P<0.001). The C statistic for NT-proBNP ≥ 900 pg/ml was significantly better than IPI score for prediction of survival. These findings suggest that NT-proBNP ≥ 900 pg/ml could be considered a useful marker for risk assessment in NHL patients treated with chemotherapy.
